主 题：Cattle Management practices Risk factors Salmonella
摘 要：A cross-sectional study was conducted to evaluate the risk factors associated with the Salmonella infection status of dairy herds in Henan and Hubei provinces,*** were assigned a Salmonella status based on the isolation of Salmonella from fecal samples obtained from adult lactating dairy *** on potential biosecurity risk factors was collected using a questionnaire template via a 15-min face-to-face interview with dairy cattle producers from May 2020 to March *** questionnaire consisted of 23 questions across two broad categories of potential biosecurity risk factors:farm and biosecurity managemental factors.A total of 48 farms were *** all(100%,48/48)of the surveyed farms,although sick animals were separated from healthy animals using fencing,there were no strict quarantine protocols for newly introduced *** species rearing was practiced in 35.4%(17/48)of the *** were removed more than once a day in 45.8%(22/48)of the farms,whereas the remainder(54.2%,26/48)only removed animal feces once a day.A total of 29.2%(14/48)of the farms were located2 km from other livestock *** use of personal protective equipment was consistently performed on all farms,with a major-ity of the workers on most farms(81.3%,39/48)always disinfecting footwear before entering production areas.A significant association between Salmonella-positive status and the high frequency of the presence of wildlife(birds and rodents in sheds and feed storage places)was recorded(OR:11.9,95%Cl:1.7,84.1,p=0.013).Fortunately,no farms shared farm equipment with other *** study highlights the occurrence of wildlife as a risk factor for the presence of Salmonella in investigated dairy *** is a need to institute appropriate on-farm control measures for wild birds and rodents to control the potential spread of Salmonella in dairy production systems.
